CARPET CLEANING- AND RENOVATING MACHINE.-

Specification of Letters Patent.

Patented Nov. 4, 1913.

I Application filed December 17, 1910. Serial No. 597,890.

To all whom it may concern Be it known that we, BERNHARD BECKER and HENRY BARRY, citizens of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Carpet Cleaning and Renovating Machine, of which the following is a specification.

The invention relates to improvements in carpet cleaning machines.

The object of the present invention is to improve the construction of carpet cleaning machines, and to provide a simple, efficient and comparatively inexpensive machine, designed for cleaning carpets, rugs and other floor coverings and analogous material, and adapted to operate separately on each individual carpet or rug, whereby the latter are cleaned in a sanitary manner and without liability of exposing one carpet to the germs of another.

A further object of the invention is to provide a carpet cleaning machine, adapted to rapidly remove the dust and dirt from a carpet, rug or the like without liability of injuring the material operated on, and capable of adjustment to suit the length of the carpet or size of the rug to be cleaned.

With these and other objects in View, the invention consists in the construction and novel combination of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended; it being understood that various changes in the form, proportion, size and minor details of construction, within the scope of the claims, may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawings :Figure l is a plan view of a carpet cleaning machine, constructed in accordance with this invention. Fig. 2

is a longitudinal sectional view on the line 2-2 of Fig. 1. Fig. 3 is a detail sectional view onthe line 33 of Fig 1. Fig. 4 is a detail perspective view of one of the oscillatory carpet carrying lever frames. Fig. 5 is a detail sectional view on the line 5-5 of Fig. 2. Fig. 6 is a detail sectional view on the line 6-6 of Fig. 3.

Like numerals of reference designate corresponding parts in all the figures of the drawings.

In the accompanying drawings illustrating the preferred embodiment of the invention, 11 designate spaced longitudinal sills of the frame of the machine. The longitudinal bars or sills are connected at their terminals by transverse bars or beams 2, which with the longitudinal bars or sills, form a rectangular base, Mounted upon the base are fixed and adjustable stands 3 and 1, which support spaced bearing brackets 5 and 6, The stands, which may be constructed of any suitable material, preferably consist of spaced legs or standards and a connecting top plate to the upper face of which the bearing brackets are secured. The legs or standards of the fixed stand 3 are bolted or otherwise secured to the base of the frame of the machine, and the legs or standards of the adjustable stand have bifurcated lower terminals 7, which straddle the side sills or bars 1. The side sills or bars 1 are provided at one end of the base with perforations 8, arranged at intervals and adapted to receive pins 9, which pierce the bifurcated ends 7 of the standards or legs of the adjustable stand and secure the latter in its adjustment. The stand tis adjustable along the base of the frame to arrange the machine to suit the size of a rug, or the length. of a piece 10 of carpet, or other ma terial operated on by the machine.

The bearing brackets 5 and 6, which are in the form of pedestals, extend upwardly from the stands and receive transverse pivots 11 and 12, consisting of rods and fulcruming longitudinally disposed oscillatory levers l3 and 14 on the bearing brackets. The rods 11 and 12 extend across the spaces between the bearing brackets, which are located at opposite sides of the frame of the machine, and the levers, which preferably consist of round bars, are provided intermediate of their ends with depending arms 15 and 16, which are bifurcated to straddle the bearing brackets 5 and 6, and the upper ends of the bearing brackets are recessed at opposite sides at 17 to receive the sides of'the arms 15 and 16 and to form reduced upper portions, which fit between the side portions of the said arms. The side portions of the arms 15 and 16 are round, and the recesses are provided with curved lower end walls, which form bearings for the arms and thereby relieve the pivoted rods 11 and 12 of strain. The levers extend inwardly and outwardly be yond the bearing brackets, and the interme- .21, cooperating with the spaced longitudinal levers to form oscillatory carpet carrying frames, and each consisting of a relatively fixed transverse bar 22, and a pivoted clamping rod or bar 23. The bar 22 is fixed to the inner ends of the oscillatory levers and projects laterally therefrom and is provided in its upper edge or face with a longitudinal groove 24: in which the carpet is clamped. The clamping rod or member 23 is provided at one end with an angularly related arm 25, extending down wardly in a slot or recess 26 of the adjacent end of the bar 22, and pivoted to the same by a transverse pin or rivet 27. The other end of the bar 22 is provided with a recess 28 to receive a locking device 29, consisting of a pin pivoted at its upper end in a perforation of the clamping rod or member 23 and provided at its lower end with an engaging head 30 of a length greater than the width of the recess 28 and adapted to be turned transversely thereof to connect the clamping rod with the relatively fixed bar 22 and lock the former in engagement with the carpet. By turning the head 30 longitudinally of the recess 28 it will pass through the same and thereby release the clamping rod or member. The inner ends 31 of the oscillatory levers are preferably reduced and secured in perforations of the relatively fixed bars of the clamps. Th oscillatory levers, which have inn-er and outer arms, are equipped at their outer arms with adjustable counter-weights 32, secured in their adjustment by clamping screws 33 and adapted to counter-balance the weight of the carpet.

The piece or strip 10 of carpet, or other floor covering extends from one oscillatory lever frame to the other, as clearly illustrated in Fig. 2 of the drawings, and the frames are oscillated to vibrate and produce a wave like motion in the strip or piece of carpet or other floor covering connected to them. The carpet is arranged between upper and lower flexible heaters 34: and 35, spaced apart a sufficient distance to permit the oscillation of the lever frames, and arranged to be engaged by the carpet to effect a beating of the same and also to relieve the carpet of strain. The vibratory or wave like motion imparted to the carpet, or other floor covering shakes the same in a rela tively gentle manner without jerking or snapping the carpet, which is caused to alternately engage the upper and lower flexible beaters. The flexible beaters check the up and down movements of the carpet and thereby prevent the strain, which would otherwise result were the carpet permitted an 'up and down movement limited only by the oscillation of the carpet carrying frames. The flexible beaters preferably consist of spaced transverse slats 36, connected by links 3? and secured at their terminals to uprights or standards 38 and 39 by hook bolts a0 and ll, or other suitable fastening devices. The hook bolts 40 and ll are linked into the terminal eyes of the links 37, which pierce the slats and form continuous chains. The upper and lower heaters are adapted to be increased in length by the addition of the slats, which are applied when the adjustable. stand is moved outwardly on the base of the frame. The flexible connections between the slats space the same to permit the escape of the dust, and

they also enable the heaters to vibrate slightly in the action of the machine.

The standards 38 are stepped in upper and lower openings 42 and 43 of the top connecting plate 14: of the fixed stand and a bottom plate 45 extending across the base of the frame and suitably secured to the side bars or sills thereof, as clearly shown in Fig. 1. The top connecting plates or portions 46 of the adjustable stand is slightly inclined, and the standards 39 are stepped in openings 47 of the said top connecting plate or portion 46, and in lower openings 48 of a transverse plate 49, extending across the frame of the machine and suitably secured to and carried by the adjustable stand. The transverse plat-es or pieces 44: and49 are located between the standards or legs of I the stands 3 and 4, and the lower terminals 50 and 51 of the uprights or standards 38 and 39 are reduced to form shoulders, which rest upon the upper faces of the transverse plates or pieces 45 and 49. The standards 38 are preferably arranged in a vertical position, and the standards 39, which are carried by the adjustable stand, are slightly inclined, being extended upwardly and inwardly, as clearly shown in Fig. 2 of the drawings.

The levers 13 are connected with arms 52 of eccentrics 53, or other suitable crank elements of a transverse shaft 54. The sleeves 18 of the levers 13 are provided with spaced depending ears between which the arms 52 fastening devices. The arms 52, which are inclined, extend upwardly and inwardly from the straps of the eccentrics 53, and the shaft 54: is journaled in suitable bearing brackets 56, mounted upon arms or extensions of thetop plate 42 of the fixed stand. A fly wheel 57 is mounted upon one end of the transverse shaft 54:, and the other end of the shaft is preferably equipped with a pulley 58, which is connected by a belt 59 with an engine, or other suitable motor for oscillating the lever frames. In practice the transverse shaft will preferably be rotated about one hundred and fifty revolutions a minute, which will cause the carpet to contact with the beaters about approximately four hundred and fifty times in five minutes, and this has been found ample for cleaning ordinary carpets and rugs. Varione other means, however, may be employed for oscillating the carpet carrying devices for shaking the carpet, and the carpet shaking devices may of course beoperated at any desired speed.
